Abstract
A seal for sealing goods in goods containers, such as freight containers, freight cars, trucks, and the like. The seal interacts with a door or other hatch that can be opened in order to seal it against unauthorized opening. The seal is activated when the goods container is loaded and is broken when the goods in the goods container are unloaded. The seal includes a transponder that includes a memory and that communicates with a communicator for the reading of information stored in the transponder memory. The seal is placed into an active mode during the sealing operation, and information as to the time when the seal is opened is stored in the transponder memory. The opening time information is subsequently read by the communicator.
